HINGE.

Application filed February My invent-ion relates to a hinge and particularly to a hinge for relatively heavy doors in which a maximum of stability is desired, combined with ease of rotation. Other objects of my invention will appear from time to timein the course of the specification and claim.

I illustrate my invention more or less diagrammatically in the accompanying drawings, wherein- Fig. 1 is a front view. r

Fig. 2 is a section on the line 22 of Fig. 1.

Fig. 3 is a section on the line 33 of Fig. 2.

Like parts are indicated by like symbols throughout the specification and drawings.

A indicates a generally flatplate or sup-- port provided on its bottom with an outwardly projecting flange A 'The plate is penetrated by aplurality of screw apertures A having-the bevelled walls A I Aligned along the central portion of the plate are aplurality of lugs B perforated as at B to receive the pivot pin B Each such lug is provided with a generally squared face B converging upon the flattened top B to form a relatively sharp corner 13'. The opposite side of the lug may be rounded or tapered as at B C generally indicates the hinge member proper having the branches C and C perforated with screw apertures C The inner end C of the hinge is rounded or inwardly inclined as at C and terminates in a plurality of tongue portions C, the intermediate ones adapted to penetrate between the lugs B and the outer ones adapted to engage the outer faces of the terminal lugs of the series. Each tongue C, is rounded at its outer end,

as at C to conform, generally to the surfaces B of the lugs. The tongues and the lugs are so proportioned that when the hinge is swung into the closed position of Fig. 2 the intermediate edges C of the hinge member,

abut against the corners B of the lugs, limiting the inward movement of the hinge, and providing a close joint.

The hinge may be inwardly reinforced,

for example, by the veins D extending to the 5 rims D surrounding some of the apertures C It will be realized that whereas I have illustrated a practical and operative device nevertheless many changes might be made 5 in the size, shape, number and disposition abutinents, the interpenetrating tongues and the abutments being apertured in line, the abutments being squared on their forward faces and rounded on their rear faces, the outer ends of the hinged tongues being.

of parts ith t. d parting from the spirit 7 I formed to conform to the round portions of the abutments, the opposed parts being so shaped and proportioned that the portions of the hinge body between the tongues closely engage the squared corners of the abutments when the hinge is in closed position.
